Abstract: The conventional constant force control methods for the deburring process have the inherent characteristic of leaving the deburred surface as an imprint of the original. In this paper, a process force model considering the burrs variations is presented to predict the contact force. An adaptive algorithm based on the impedance control is used to reduce the burrs effect on the machined surface. The specified contact force in normal direction and the feed rate is adjusted automatically according to the burrs sizes to achieve the desired chamfer depth compliantly. The simulation experiment is carried out to verify the effectiveness of the approach. The performance of the adaptive impedance controller is compared with the conventional impedance control.
